The Uruguayan Blancos, when attacked by Brazil,…
November 1864 CE
The Uruguayan Blancos, when attacked by Brazil, had asked for help from Paraguay, but López has not directly come to his ally's aid.
Instead, on November 12, 1864, the Paraguayan ship Tacuarí captures the Brazilian merchant steamer Marquês de Olinda, which had sailed up the Río Paraguay to the province of Mato Grosso.
Impounding the Marqués de Olinda in the harbor of Asunción, López imprisons the Brazilian governor of the province of Mato Grosso, who had been on board.
